I wouldn't say there is too much sex in pop culture. I would say there aren't enough parents being parents in society. Lets face it the media could show whatever the heck they want. If parents would pay attention to what their kids are watching they would know what shows to allow them to watch. If they don't want them watching something like sexual content, they can keep it from them. Violence, same deal.
Don't get me wrong, I'm far from a prude. Heck, my parents who were die hard Republicans were also nudists. But it's all in HOW the sexual content is presented. I mean showing a hardcore sex scene as opposed to an actual love scene could make the difference in whether it's acceptable for a kid to see. It also depends on the age of the child too. Really it comes down to the parent deciding whether the kid is ready for the information. Or as I said... Parents being PARENTS
